Fatal error: you must enable the intl extension to use CakePHP

Question

I successfully installed the PHP intl extension, I noticed that I had to enable the intl extension in the php.ini file, removing the semicolon, and when I received this warning, I was told that the extension was already loaded, so I edited php. ini again and again add a semicolon for the expression "extension = intl.so" this way: "extension = intl.so" as though the same error from CakePHP never occurred, I don’t know if the extension is really loaded or not.

Note. I am using Mac OS X version 10.12.4 PHP version 5.6.30
